I am in grad school and am not planning to take out any more loans.  Can I apply for IBR while I am still a student or do I have to wait until I graduate?  I have used the online estimator and it appears that it would be quite beneficial to start now.  I am a full time teacher and would like to repay on IBR and start the clock on PSLF as soon as possible.

Sorry, Laura, this one got past me.

When you are in school more than 1/2 time, your loans are placed into in school deferment.  You should be able to get your undergraduate loans out of deferment and choose IBR now, but it’s going to be a bit of work, since the system is designed to automatically place them into deferment, and you’ll need to make a number of calls and potentially write some letters.
